I cant get “Replies To”

when i click on “replies created” or “replies to” button in my bbpress forum i cant get any replies created by a user! how can i do this? actually i installed bbpress beside buddypress inside WordPress! everything seems fine but i cant get this. Topics created by user work just fine but replies don’t!
i found out “user-topics-created.php” controls topics created inside bbpress but we dont have such file for Replies! like “user-replies-created.php”!! Any help will be appreciate.
